Ultra-Low Power Single push button ON/OFF controller based on ATTiny13/13A/25/45/85 for other MicroController and circuits application.

• Ultra-Low Power 000.2uA (200nA)
• Supported uControllers: ATTiny13/13A/25/45/85
• Single push button ON/OFF

• Ultra-Low Power 000.2uA (200nA)
• Supported uControllers: ATTiny13/13A/25/45/85
• Hold down button to ON/OFF
• External Shut down signal from other Micro-controllers or circuits

Please upload the bootloader first, then upload the code.

• Use ATTinyCore for ATTiny25/45/85:https://github.com/SpenceKonde/ATTinyCore
• Use MicroCore for ATTiny13/13A:https://github.com/MCUdude/MicroCore

Arduino setup for ATTiny13/13A:

• BOD: BOD Disabled
• Bootloader: No bootloader
• Clock: 128 KHz internal osc
• EEPROM: EEPROM not retained

Arduino setup for ATTiny25/45/85:

• Board: "ATtiny25/45/85 (No bootloader)"
• B.O.D. Level (Only set on bootload): "B.O.D. Disabled (saves power)"
• Chip: "ATtiny45"
• Clock Source (Only set on bootload): "128 kHz (internal WDT)"
• Save EEPROM (only set on bootload): "EEPROM not retained"
• LTO (1.6.11+ only): "Disabled"
• millis()/micros(): "Disabled (saves flash)"
• Timer 1 Clock: "CPU (CPU frequency)"
